PATENT BRASS ROI? AND TUBING.

rods and tubing used more particularly in the manufacture of bedsteadsand other articles of furniture; and it consists in the peculiar finishof the exterior, which I term needle finish, from the fact that thesurface thereof is thickly covered with numerous minute holes,punctures, or indentations, without destroying in the slightest thefinish or polish of the said surface.

The object of the needle-finish as applied to brass or copper rods andtubes, to be made up into tables, beds, and other similar articles, isfor the purpose of destroying the effect of scratches, to which such areconstantly subjected, and to obscure them, so that theirpresence will beunnoticeable, audit has been found in practice to be effective andextremely desirable for the purpose intended.

Referring to the drawings, Figure l repre sents a section of tubing usedin the manufacture of brass stock, showing the indentations, &c., andFig. 2 a sectional side view of tubing with a section cut away.

Arepresents thebodyof the tube,andaaa are indentations formed closelyupon the surface and around said rod, which indentations or minutepunctures are preferably formed thereon by passing the same through orbetween rolls provided with numerous needle-points or similarprojections, although it is obvious that the punctures or indentationsmay be otherwise formed, the object being to have the indentationsexceedingly small and close together, in order to avoid accumulation andthe holding of dust and dirt within them, for it has been foundinpractice that coarse indentations, or those formed upon such surfaces byblunt projections, do not retain the polish and luster like those withthe fine minute pricks.

I sometimes prepare the plates with punctures or indentations beforethey are formed into rods or tubing by passing the plate from b whichthey are to be made beneath a roll or rolls provided with theneedle-points or projections. I do not wishto be understood, however,that I claim, broadly, a rod or tube provided with a roughened orindented surface, as I am aware that such have been figured by rollingand by casting; such, however, I do not claim; but,

Having thus set forth my invention, What I claim as new, and desire tosecure by Letters Patent ofthe United States of America, is-

1. As an improved article of manufacture, a needle-finished rod or tubeof brass or copper, the surface of which is provided with numerousminute punctures or indentations, substantially as shown and described.

2. Finishing brass and other polished metallic rods or plates bypuncturing or indenting the surface thereof with minute pricks,substantially as and for the purpose set forth.
